ABSTRACT:
A fabricated cup or other nestable container in which the sidewall is formed from a rectangular sheet-like blank of a thermoplastic material, particularly an expanded thermoplastic material, the blank having its ends joined to one another in a liquid-tight seam extending the full height thereof to form a sleeve, the blank having a relatively high degree of orientation or heat-shrinkability extending circumferentially of the sleeve, the fabrication of the sidewall from the sleeve being accomplished by telescoping the sleeve over a generally frusto-conically shaped mandrel, by exposing the sleeve to heat to cause it shrink to conform to the configuration of the mandrel and by stripping the shrunken sleeve from the mandrel. A two-piece container may also be formed from such a sidewall by affixing an end closure element to the bottom or smaller end of the sidewall. A one-piece container may also be formed in this manner by using a blank of sufficient height so that a substantial portion of the sleeve formed therefrom extends beyond the smaller end of the forming mandrel, such substantial portion, when the sleeve is exposed to heat, being shrinkable to form an annular planar portion disposed transversely of the longitudinal axis of the mandrel and a relatively small tubulation which extends longitudinally from the interior of the annular planar portion and which, by the application of pressure thereto while at elevated temperature, may be caused to collapse and fuse together to close the bottom of the container in a liquid-tight manner. A container of this type may be used to advantage to contain any liquid or other fluent product therein in face to face contact with the interior surface of the sidewall thereof, and when the container is fabricated from an expanded material, because of the insulating characteristics of such material, a container fabricated therefrom may be used to particular advantage as a handholdable cup for coffee or other hot beverage.
